Fleabane
At one point today I needed to get out of the office. It was a lovely if somewhat warm day and I went to the empty lot next to my building. The western part of that is mostly woods now, having been empty for about 25 years. The eastern part is much more open and covered with a waist-deep herbaceous perennial of some sort (I really should look it up). Anyway, I took some pictures of this fleabane. I don’t know for sure what it is but my guess is annual fleabane (Erigeron annuus).
